why do most herbivorous animals eat only the leaves?

169 viewsBiologyOther

Some herbvivores also eat the roots, fruits, and the flowers, but most herbivores mainly eat the green leaves right? I understand animals not eating the whole tree trunk, but if some animals can eat roots, surely they can eat the branches too right? I tried googling but I couldn’t find anything other than insects specialized in eat through tree barks.

Evolution selected for the herbivores that didn’t kill their food source. Leaves grow back.
